 Gm is conducting a recall on all subject vehicles build between may 1999 and october 14, 1999.significant changes were incorporated into production in early october 1999, and vehicles built after that date have lower warranty failure rates.the complaint and warranty data appear to support the effectiveness of these changes. gm made additional changes in november 1999, february 2000, may 2001, and february 2004.odi will continue to monitor this problem and will take further action, if warranted, in the future.for further technical details see the attached engineering analysis report.

 (1) antilock brakes engaging when not necessary (2) when brakes were applied the antilock brakes were engaged making normal braking less effective and because of this problem, one time pulling into our driveway when applying brakes, the truck didn't stop in time and was smashed into the back of another truck sitting in driveway (3) the truck was taken to get this problem fixed which required the installation of a new speed sensor on driver's front side which was broke in half and a gm sensor operation on both front bearings was performed. *nm

 I purchased a 2002 chevrolet pickup (vehical serial # 1gcek14w82z42909 ) in august of 2002 from whitaker & son, sidney, n. y. on 10/ 31/o3. i was purchasing tires from kost tire. binghamton, n.y. and was notified that rear brake rotor was deteriortating. i then took the truck (26,744 mileage) back to whitaker and son and the deteriorating rotor and brake work was accomplished on 11/6/03 under warranty. i was told that this brake system deterioration was not unusal. i was told that general motors was frantically working on the problem and it was only occurring in the n.e., u.s.a. where a lot of salt is used on the roads in the winter to deice the roads. then in may 2005 i heard a grinding sound when the brakes were applied. i therefore brought the truck (mileage 62,058 miles) back to whitaker and the rear brake rotors & pads were replaced. i contacted general motors and then whitaker and i was told this brake problem was in all makes of vehicles with rear disc brkaes in the northeast u.s.a. from the year 1999- 2004. i did pay the whitaker & son, inc. bill for the brake problem on 7/14/05. i have talked to 2 other mechanics cocnerning this problem and they said it was occurring. they were replacing a lot of rusted and pitted rear disc brake rotors. paul vetrone, vetrone motor sales, e. front st. in hancock, n.y. (vehicle repair and towing) said rotor repladcement is occurring quite systematically every 20,000 miles or so. also my son uses a chevy pickup 2004 and the rear brake rotor deteriorated on this company vehicle after only 18,000 miles. general motors advertises the the pickups as being stong llike a rock put does not inform anyone that they will most likely be replacing rear disc brake rotors every 18,000 to 26,000 miles. the operators manuel does not say to replace the rear disc brake rotors every 18,000.
